The Bug
The Swift Sneak enchantment was made to be applied to leggings in the latest snapshot (22w12a as of making this bug report). However, through the anvil, Swift Sneak can be applied to boots as well. The enchantment does not do anything when on boots, but applying the enchantment to boots is not intended as the changelog states that the enchantment is unique to leggings.
Steps to Reproduce
Grab an anvil, any boots, and any level of Swift Sneak
Place down the anvil and right click on it to open the GUI
Put the leggings and the Swift Sneak book into the anvil slots
Observed Result
Swift Sneak can be applied to boots
Expected Result
Swift Sneak cannot be applied to boots
